利用matlab写的检测椭圆参数的算法，利用hof变换以及相关的椭圆特征提取算法，能将任意的椭圆长短轴参数以及椭圆心进行标注出来-The use of matlab to write detection algorithm of elliptic parameter, using the hof transformation as well as relevant ellipse feature extraction algorithm, can be arbitrary elliptic axle parameters of the ellipse and heart to be marked
